A NASA study based on an innovative technique for crunching torrents of satellite data provides the clearest picture yet of changes in Antarctic ice flow into the ocean. The findings confirm accelerating ice losses from the West Antarctic Ice Sheet and reveal surprisingly steady rates of flow from its much larger neighbor to the east.

New CU Boulder-led research has established a causal link between climate warming and the localized extinction of a common Rocky Mountain flowering plant, a result that could serve as a herald of future population declines.

Peaking global CO2 emissions as soon as possible is crucial for limiting the risks of sea-level rise, even if global warming is limited to well below 2°C. A study now published in the journal Nature Communications analyzes for the first time the sea-level legacy until 2300 within the constraints of the Paris Agreement.

Recent changes to vegetation cover are causing the Earth's surface to heat up. Activities like cutting down evergreen forests for agricultural expansion in the tropics create energy imbalances that lead to higher local surface temperatures and contribute to global warming.

The reality of climate change poses a significant threat to global biodiversity. As temperatures rise, the survival of individual species will ultimately depend on their ability to adapt to changes in habitat and their interactions with other species.

Nitrate deposits in the Arctic remains high even after the turn of the century, despite environmental policies adopted by neighboring countries in the late 20th century to cut nitrogen oxide (NOx) emissions.
